Product Description
Galvanized pipe, also known as galvanized steel pipe, is divided into hot-dip galvanized and electro-galvanized. The hot-dip galvanized layer is thick, the coating is uniform, the adhesion is strong, and the service life is long. The cost of electroplating is low, the surface is not smooth, and the corrosion resistance is worse than that of hot-dip galvanized pipe. Galvanized pipes include galvanized round pipes, galvanized square pipes, galvanized seamless pipes, galvanized welded pipes, etc.
Ordinary galvanized steel pipes are seamed steel pipes. Galvanized steel pipes are only available on special request. The way to distinguish between seamed and seamless steel pipes is to measure the outer diameter of the pipe. The manufacturing standards of the two steel pipes are different, and the outer diameters are also different. For example, for a steel pipe with a diameter of 100mm, the outer diameter of the seamed one is 114mm, and that of the seamless one is 108mm.

Galvanized pipes must have an adherent and continuous layer of zinc on the interior and exterior surface. The covering with zinc of both surfaces or only the inner surface is achieved by submersion in a molten zinc bath. Local roughness and thickening of the zinc layer is allowed, mainly on a portion of 80 mm from the end of the pipe, where the blowing of the tubes is executed. The thickness of the zinc layer on the outer surface must be thinner than the layer of the inner surface. The thickness of the interior surface must be approximately 56 µm. The linear mass of galvanised pipes is calculated by adding the mass of the coresponding minimal thickness of the zinc layer to the mass of the pipes.
Application of galvanized steel pipe
Galvanized pipes are widely used. In addition to being used as pipeline pipes for general low-pressure fluids such as water, gas, and oil, they are also used as oil well pipes and oil pipelines in the petroleum industry, especially offshore oil fields, and oil heaters and condensation pipes for chemical coking equipment. Pipes for coolers, coal distillation washing oil exchangers, trestle piles, and support pipes for mine tunnels, etc. Widely used in construction, machinery, coal mines, chemicals, electric power, railway vehicles, automobile industry, highways, bridges, containers, sports facilities, agricultural machinery, petroleum machinery, prospecting machinery, greenhouse construction and other manufacturing industries.
